Answer»

Follow BODMAS rule to solve this question, as per the order given below,

Step-1- PARTS of an equation enclosed in 'Brackets' must be solved first, and in the bracket,

Step-2- Any mathematical 'Of' or 'Exponent' must be solved next,

Step-3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Given expression is,

$(45{\RM{\% \;of}}\SQRT {\LEFT( {255\; \div \;34\; \times \;146 - 6} \right)}+ \frac{7}{{12}}of\;{\left( {5.4} \right)^2}\; = \;?)$

Applying BODMAS Rule;

⇒ $(45{\rm{\% \;of}}\sqrt {\left( {7.5 \times 146 - 6\;} \right)}+ \frac{7}{{12}}of\;{\left( {5.4} \right)^2} = ?)$

⇒ $(45{\rm{\% \;of}}\sqrt {\left( {1089} \right)}+ \frac{7}{{12}}of\;29.16 = ?)$

⇒ 45% of 33 + 17.01 = ?

⇒ 14.85 + 17.01 = ?

∴ ? = 31.86
